NC.4.NF.2 Compare two fractions with different numerators and different denominators, using the denominators 2, 3, 4,
5, 6, 8, 10, 12, and 100. Recognize that comparisons are valid only when the two fractions refer to the same whole.

NC.4.NF.1 Explain why a fraction is equivalent to another fraction by using area and length fraction models, with
attention to how the number and size of the parts differ even though the two fractions themselves are the same size.

NC.4.NBT.6 Find whole-number quotients and remainders with up to three-digit dividends and one-digit divisors
with place value understanding using rectangular arrays, area models, repeated subtraction, partial quotients,
properties of operations, and/or the relationship between multiplication and division.
